Super difficult mobile phone activation error

The mobile phone restores the system, and re-activation shows that there is an activation error. I have tried all the methods that can be tried, including activation with the official software, and re-frashing the system shows that there is an activation error. Personally, I initially suspect that it is a motherboard problem.

Have you tried putting in a working sim card, let the device sync to the server and retry activation?
